Explanation of Names
Xestobium rufovillosum (DeGeer 1774)
common name is derived from adults tapping on wood to attract a mate: males and females call each other by striking the surface of wood, which some interpreted as death knocking at the door(1)
6–7.5 mm(1)
subcosmopolitan, native to Europe, adventive in NA(2)(3) [New England, IL(4)]
in oak and especially wood that has been previously attacked by decay fungi; indoors it usually infests wood that has been exposed to excessive moisture(1)
Life Cycle
takes 2–3 (up to 10) years; adults do not feed and live about 10 weeks(1)
adults probably do not fly, but can raise wing covers and flutter hind wings; tapping is usually heard in spring when adults emerge(1)
